1 General
The Vega HB-3PLUS Headset Interface Box is a reliable method for connecting a desk microphone,
headsets and footswitch controls to any computer running Vega’s C-Soft program or any Vega dispatch
console. A bi-color front panel LED indicates power (green) or active PTT (red).
The HB-3PLUS connects directly to the handset jack of the dispatch control console or a PC operating
with the Vega C-Soft dispatch software. In the console mode, an RJ-H 4 conductor cable provides the
connection from the HB-3PLUS to the console. Connections to the PC serial port and sound card provide
PTT, monitor, relay and Aux input control in the PC mode.
The HB-3PLUS also provides a connection to any telephone device with a NENA I/O port, allowing for a
single headset to be shared by the radio and phone system. When the phone set is taken off-hook, the
headset microphone audio is routed to the phone system and selected radio is transferred back to the
SELECT speaker. Telephone audio is routed to the headset as long as the system is off-hook.
